This blog summarizes the webinar that Fluigent and Zurich Instruments presented together our solution for fast electric impedance spectroscopy (EIS) in microfluidics. The system consisted of an HF2LI lock-in amplifier from Zurich Instruments and the LineUp series microfluidic flow controllers […]

Proximity sensors: inductive or capacitive? Using the MFIA to measure the sensitivity and response time of both sensing regimes

on January 7, 2021 at 5:36 pm by Meng
Introduction A proximity sensor is a sensor that detects nearby objects without physical contact [1]. They are commonly used, in applications ranging from production lines to modern mobile devices, mainly thanks to their non-contact configuration and the accompanying long lifetime. […]
